Cross-border tax compliance, foreign income reporting, and US international tax obligations for individuals and corporations
Section 988 of the Internal Revenue Code makes foreign-exchange gains and losses ordinary, not capital. Importers, exporters, and remote workers paid in euros or pounds get full ordinary-loss deductions with no $3,000 cap, a same-day election to convert forward-contract gains to capital, and a $200 per-transaction de minimis exception for personal travel currency.
Form 3520-A is the annual information return for a foreign trust with a U.S. owner, due March 15. If the foreign trustee does not file, Section 6677 imposes an initial 5% penalty on trust assets plus $10,000 per 30-day continuation period — payable by the U.S. owner. Covers who files, the substitute filing path, the reasonable-cause defense, and how to clean up multi-year non-compliance.
Section 7874 imposes a 10-year inversion-gain floor when former U.S. shareholders own 60-80% of a new foreign parent and reclassifies the parent as a domestic corporation at 80%. The only escape is the substantial business activities safe harbor, which requires clearing a 25% bright-line threshold on employees, tangible assets, and gross income in the foreign country.
How willful non-filers, crypto whales, and offshore account holders use IRS Form 14457 to trade criminal exposure for a defined six-year civil resolution under the Voluntary Disclosure Practice — including the December 2025 proposed framework, disqualifying traps, and when to choose Streamlined or DIIRSP instead.
Nonresident aliens who own U.S. real estate, U.S. corporate stock, or other situs property get only a $60,000 estate tax exemption — not the $13.99 million citizens enjoy in 2026 — and pay up to 40% on the excess. A working guide to Form 706-NA, FIRPTA withholding, treaty relief via Form 8833, transfer certificates, and the blocker-corporation structures that actually work.
Form 8858 reports foreign disregarded entities and foreign branches on a U.S. return, and missing one carries a $10,000 penalty per entity per year that can snowball to $50,000 after IRS notice. This guide covers who must file, Schedules C through M, Section 987 currency calculations, the Schedule K-2/K-3 box 11 connection for Category 6 filers, and the four paths back into compliance.
Section 1446(f) requires buyers of partnership interests to withhold 10% of the amount realized when a foreign partner sells and remit it to the IRS within 20 days on Form 8288. This guide walks through the six exceptions, the certifications that must be in hand before closing, and the bookkeeping records that defend the position under audit.
Section 245A grants a 100% dividends-received deduction on qualifying foreign dividends to U.S. C corporations, but only when the 365-day holding period, hybrid dividend, extraordinary disposition, and PTEP ordering rules all hold. This guide explains how the participation exemption coordinates with GILTI and Subpart F, the traps that disqualify the deduction, and the bookkeeping that keeps it defensible on audit.
Section 367 overrides corporate non-recognition rules the moment U.S. property crosses into a foreign corporation, forcing immediate gain on outbound asset and IP transfers. This guide explains Sections 367(a), (b), (d), and (e), the GRA and Form 8838 deferral path, the 10% Form 926 penalty, the TCJA expansion to goodwill and workforce in place, and the 2024 final regulations on IP repatriation.
A practical walkthrough of IRC Section 7701(b) for globally mobile founders — the 31-day floor, the weighted three-year 183-day formula, exempt-individual rules, the closer connection exception (Form 8840), and treaty tie-breakers (Form 8833) — with a worked example showing how 130 U.S. days in 2026 can trigger worldwide taxation.
Section 1248 recharacterizes part of a U.S. shareholder's gain on the sale of CFC stock as a dividend, capped by the corporation's earnings and profits and reduced by PTEP from GILTI and Subpart F inclusions. This guide explains who is affected, how the lookback works, why corporate sellers can prefer the recharacterization for Section 245A, and how to build a defensible work paper.
Form 6166 is the IRS-issued certificate of U.S. tax residency that unlocks reduced foreign withholding under bilateral tax treaties. Apply with Form 8802 — $85 for individuals, $185 for entities — and one filing covers unlimited countries and certificates, often saving five or six figures per cross-border contract.
